'rxrnwnrrme MACHINE.

Application filed June 2,1923. Serial No, 642,961.

To all whom it may concern:

Be it known that 1, JOHN VVALDHEIM, a citizen of the United States, residin in Elizabeth. in the county of Union and tate of New Jersy, have invented certain new and useful Improvements in Typewriting Machines, of which the following is aspecification.

This invention relates to machines for T0 typing upon continuous work-webs, each crimprising a plurality of superimposed p 1es, printed forms in register, the plies being separate in some cases. andin other cases being joined at their side edges to form fanfold webs.

In such machines, after typing has been effected on the form on the outside ply and carbon copies made on the inner plies by means of interleaved carbon-sheets,-the carbon-sheets and the web-plies are shifted relatively to each other to enable the carbonsheets to be used with a fresh set of forms. It has been found impracticable to'efi'ect such relative shifting while the web-plies and interleaved carbons are bent'around a considerable part of a usual round platen.

Consequently, it has been the practice in the Underwood continuous billing machine, to displace the platen upwardly to permit the plies to bestraightened thereunder and the carbon-sheets to be retracted by a carboncarrier on a substantially horizontal table extending rearwardly from the carriage.

It has. however, been found practicable to effect relative shifting of the web-plies. and the carbon-sheets when they are bent around a curved support of comparatively large radius, and therefore by the provision of suitable means at the rear of the typewriter to permit the use of the standard typewriter without any provision for upward displacement of the platen.

be made of a carbon-carrier of substantially the usual form mounted for forward and usually provided with successive In carrying out the present invention,

the rear of the platen are supported and;

rearward movement over said table. When, therefore, typing has been effected on one set of forms the usual feed-rolls may be cast off and both the web-plies and interleaved carhon-sheets drawn rearwardly bythe carboncarrier until the forward ends of the carbonsheets have been retracted to the rear of the platen. The feed-rolls may thenbe cast on sheets and web-plies is completed. the earbon-carrier is released and the carbon-sheets advanced with the web-plies to an extent determined by a second'gageat the delivery side of the platen and positioned to gage the web-plies for severing the used portions of the webs by means of the usual knife and for peginning the typing on the next set of orms.

To retract the carbon-carrier, provision including-a link and two gear segments to a transverse shaft having fixed thereon, at its middle. an arm with a forked end engaging a rod beneath the table and extending from end to end of the carbon-carrier beneath the table, so that the arm may be in effective engagement with the rod irrespective of the position ofthe typewriter-carriage.

To prevent relative displacement between the web-plies and the carbon'sheets and also to relieve the, carbon-sheets of unnecessary strain during the rearward movement of the carbon-carrier, provision is made of a device for clamping the web-plies at the rear edge of the carbon-carrier, and of means for automatically releasing the clamp when the carbon-carrier is retracted to the full extent, thereby permitting the web-plies to be advanced while the carbon-sheets are held stationary.

- It should be understood that the distance between the two forward edge gages is equal to the distance between the extreme rearward position of the forward ends of the carbon-sheets and their position whenready v the platen are fixed together, so that only one adjustment is necessary when a change is made from one length of form to another.

Other features and advantages will hereinafter appear.

In'the accompanying drawings,

Figure 1 is a side elevation, showing the invention applied to an Underwood standard typewriting machine, the work-web and the carbons being in the positions assumed during the typing of a form.

Figure 2 is a top view of the structure shown in Figure 1, part of the curved table being broken away to.show the underlying,

structure.

Figure 3 is a view similar to Figure 1,

but showing the carbons and work-web in the positions assumed when the feed-rolls are cast off and the carbon-carrier is retracted to its limiting position.

Figure 4 is a view showing the work-web in gaged position after being drawn forward by the platen while the. carbon-sheets are held against forward movement by the carbon-carrier.

Figure 5 is a View showing the work-web and the carbon-sheets advanced together from the positions shown in Figure 4 to such positions that when the typed forms at the leading end of the work-web are torn off, typing may be begun on the next set of superimposed forms.

A platen 11 is journaled in theends 12 of a platen-frame 13 comprising a rear paper-table 14 and forming part of a carriage 15 supported at its rear on a rail 16 fixed to the typewriter frame 17. The typewriter frame 17 is mounted on a base 18, which also serves to support a -frame 19. having fixed thereto at its rear a rail 20 to support the rear end of a rearward extension 21 of the carriage 15. The extension 21 comprises a curved table 22 mounted on a frame comprising two curved side members 23 and front and rear cross-members 24 and 25, respectively. At its front the extension 21 is connected to the carriage by means of brackets 26 secured to the carriage b means of screws 27, and secured to the sic e members 23 by screws 28. At its rear the extension 21 is supported on the rail 20 by means of a roll 29 resting thereon and pivotally mounted on a central bracket 30, secured to the cross-rod 25 and having its lower end extending forwardly beneath the rail 20 to prevent the roll 29 from being lifted there from.

Mounted on the. table 22 is a carboncarrier 32 having adjacent its edges, on the lower side thereof, grooved rolls 33 en aging the edges of the table 22. The car oncarrier 32 has stepped blocks 34 at opposite ends thereof, and projecting inwardly from said blocks 34 are detachable carbon-blades 35, to which are secured the rear ends of carbon-sheets 36.

F or retracting the carbon-carrier 32, provision is made of a handle 37 mounted to swing about a pivot 38 on the right-hand side of the typewriter frame, said handle 37 being connected by aulink 39 with an arm 40 mounted on a pivot 41, and having at its upper end a toothed sector 42 in mesh with a toothed sector 43 fixed on a shaft 44 journaled in arms 45 extending upwardly from the sides of the frame 19. When the handle 37 is swung forwardly the shaft-44 will be turned in a counter-clockwise direction, Figures 1 and 3," and, by means of an arm 46 fixed on the shaft 44 near its middle point, will shift the carbon-carrier 32 rearwardly, the connection between the arm 46 and the carbon-carrier being effected by engagement of a fork at the upper end of the arm 46 with a rod 47 inside of the side members23, and supported at its-ends in brackets 48 projecting downwardlly from the sides of the carbon-carrier 32.

The carbon-carrier 32 is provided near its rear edge with a work-web clamp comprising a fixed bar or jaw 49 and a co-operating bar or jaw 50 mounted on arms 51- pivoted at 52 on ears 53 projecting upwardly from the carbon-carrier at opposite edges thereof, the

bar 50 being pressed toward the bar'49 by a spring 54 attached at one end to one of said arms 51 and at the other to the carbon-carrier 32. One of the arms 51 is provided with acam-extension 55 to co-operate with a pin 56 on an arm 57 attached to the extension 21 to move the bar 50 away from the bar 49 when the carbon-carrier 32 reaches the position shown in Figure 3' with the clamping bar 49 thereof resting on a stop 58 fixed to the table 22.

When the machine is to be used, the carbon-carrier 32.is brought to a convenient po sition and the clamping bar 50 separated from the bar 49 to permit the plies 59 of a work-web 60 to be drawn through the carbon-carrier. When a suitable length of the work-web 60 has been drawn between the clamping bars 49 and 50, the clamping bar 50 may be released to press the web against the bar 49. All of the plies 59, except the one to pass around the platen on the outside, are lifted, and a carbon-sheet 36 is then inserted in the opening thus formed, and the carbon-blade 35 to which the carbon-sheet is attached is connected with the stepped support or bl0ck'34 at the left-hand side of the carbon-carrier. The next ply 59 is then placed on the carbon-sheet just inserted and the web-ply or plies lying outside thereof on the table 22 are held away therefrom to form an opening in which is placed a second carbon-sheethaving its rear end attached to a second carbon-blade 35, which, in'turn, is attached to the block 34 on the right-hand side of the carbon-carrier. The carbonsheets 36 are made of such length that when the carbon-carrier is in its rearward position the forward endsof the carbon-sheets will lie to therear of the platen, as shown in Figure 3.

Furthermore, in interleaving the carbonsheets 36 between the plies 59 theyare so positioned that the forward ends of the plies extend beyond the ends of the carbon-sheets, as indicated in Figure 3. The forward ends of the plies59 may then be inserted between the platen l1 and feed-rolls, whichmay be the usual rear feed-rolls 61, the machine being equipped with the usual rear and front feed-rolls 61and 62, respectively, carried by arms 63 and 64, which are controlled by the usual cast-off shaft 65 connected in the usual manner with a cast-off finger-piece 66. After the forward ends of the plies 59 have been inserted between the platen and the cast-off rear feed-rolls, the feed-rolls may be restored and the platen advanced, by means of a finger-wheel 67 or the usual line-spacing mechanism including a ratchet-wheel 68, to pass beneath a knife 69 supported above a front paper-table 70 mounted on a bar 71, which, in turn, is supported by brackets 72 on the sides or ends 12 of the platen-frame. Provision is also made of a gage-bar 73 extending upwardly and rearwardly in the same general direction as the table 70. The advance of the plies 59 is continued until the forward ends thereof align with a gage 74, the carbon-carrier being held in its rearward position during such movement. The carbon-carrier 32 which has been held'in its rearward position, preferably by means of the handle 37, is then released and the webplics 59 and interleaved carbon-sheets 36 are fed forward until the forward ends of the plies 59 contact with a gage positioned at the length of one form from the edge of the knife 69. If'then the first set of forms is severed by means of the knife 69 asecond set of forms and the carbon-sheets will be in position to begin typing thereon, as indi-' In this connection it connected by means'of a connector or bar 76,

the adjustment of the gages being effected by positioning the gage 75 at a distance from the knife 69 equal to the length of the formto be used. As herein disclosed, the gage 74 is the end of the bar .76., When saidgages 74 and 75 have been placed in adjusted position. they may be secured by suitable means such as a screw 77. Preferably the gage-bar is provided with numbered graduations 78 indicating the distances from the edge of the knife 69.

. ,After the second set of forms on the plies 59 is positioned as shown in Figure 5, typing is effected thereon and the plies 59 and carbon-sheets 36 are advanced until the typing on the set of forms is completed, as indicated in Figure 1. The feed-rolls are then cast off and the carbon-carrier 32 moved rearwardly to its Figure 3 position by means of the handle 37. The feed-rolls 61 and 62 are then thrown on by means of thefinger-piece 66 and the, platen rotated until the forward edges of the plies 59 contact with the. gage 74. The carbon-carrier 32 is then released and the plies 59 and carbonsheets 36 are. fed together until the forward ends of the plies 59 are brought into. engagelnent withthe gage 75, Figure 5. The used forms arethen severed and the third set of forms is in position for typing.

Although the manner, just described, of positioning the plies and carbon-sheets to start typing appears to be the most.prac ticable, it should be understood that it may be done in other Ways, as, for example, by positioning the forward edges of the first set of forms the proper distance beyond the ends of the carbon-sheets 36. Obviously, if this method is followed, typing may be of fected on the first set of forms.

. It will be understood that, if desired, the device may be used without the clamping bar 50, the carbons being effective when curved around the platen with the worksheets to draw the work-sheetsrearwardly when the carbon-carrier 32 is moved back to the stop 58. This, however, puts the carbons under considerable tension, which may result in accidentally tearing them. Consequently the clamping bar 50 has been pro vlded to relieve the carbons of any strain and thus avoid tearing of the carbons.

Variations may be resorted to within the scope of the invention, and ortions of the improvements may be used without others.
